REGISTER FoR on. DELIVERED.

SPECIFICATION forming part of Letters Patent No. 543,941, dated August 6, 1895.

Application filed April 15, 1 8 95.

siding at Cincinnati, Hamilton county, Ohio,

and JOHN H. LOHSTROH, residing at Newport, Campbell county, Kentucky, citizens of the United States, have invented certain new and useful Improvements in Registers; and we do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the annexed drawings, which form a part of this specification.

This invention comprises a'register that has been designed more especially for enabling drivers of oil-delivery wagons to keep an ac curate account of the oil furnished to grocers and other 'retail dealers; and our improvement includes a specific combination of devices that prevent any part of the register being injured in case an operating-lever of the same should be operated after a hand has made one complete rotation in front of a numbered dial, the details of said combination being hereinafter more fully described, and then pointed out in the claim.

In the annexed drawings, Figure 1 is a front elevation of our improved register, the glass of the inclosing-case being removed. Fig. 2 is an enlarged front elevation of aportion of the operating mechanism. Fig. 3 isva rear elevation of said mechanism, the registeringdisks being omitted therefrom. Fig. 4 is an enlarged vertical section of a ratchet-wheel and its accessories, said section being taken in the plane of the main shaft of the register. Fig. 5 is an enlarged transverse section of a portion of a spool journaled on said shaft. Fig. 6 is an elevation of a stop-plate carried by said shaft, thelatter being sectioned. Fig. 7 is a plan of the registering-disks.

The inclosing-case A has a glass front that protects the mechanism and contains a pair of plates B B that carry the operative parts of our register, the front plate B being provided witha dial or face C. This dial may be graduated in any suitable manner; but in the present instance it has twenty equal divisions, numbered up to 100, for a purpose that will be described hereinafter. Adapted to travel around in front of this dial is an ordinary hand or pointer 0 applied to the outer end of a sleeve D, as more clearly shown Serial No, 5l5f740. (No model.)

in Fig. 4, the sleeve beingimmovably secured to a spool or grooved drum E to which is fastened one end of acord or light wire F, the other end thereof being carried down through the case and provided with a ring or other suitable pull f. Furthermore, this drum has a projecting pin e, adapted atthe proper moment to contact with a lug g, extendinglaterally from the lower portion of a vibrating stop plate G, hung upon the sleeve D, as more clearly seen in Fig. 6,aslot g being arranged above this lug to receive a short stud b. This stud projects rearwardly from the front plate B and limits the swingof said plate G both to the right and left.

Sleeve D fits so snugly around a mainshaft II, as to turn in unison therewith when the register is operated in a proper manner; but if the operating-cord 7c is pulled after the pointer c has indicated 100 said sleeve will then rotate around said shaft without advancing said pointer another degree. ShaftH is turned by a ratchet-wheel I secured thereto, and the wheel is operated byapawlj,pivoted to the rear side of a lever J, the hub of which j is hung upon said shaft and is fitted between the opposing faces of said wheel and spool E, the exposed or free end of said lever having a rod K coupled to it. This 110d has a tappet k for operating a bell-striker L, that gives one blow on a gong M every time said rod is pulled down. This act is accomplished by pulling on a handle secured to the lower end of a cord attached to said rod, it being understood that the register is to be secured at such .an elevation as to render it inconvenient to reach the ringf.

N is a spring that maintains the lever J in its normal or elevated position, the front of said lever having an adjustable coupler O pivoted to it, and the lower end of this coupler being engaged with a lever P, carrying a pawl R that is held in gear with a ratchetdisk S by a spring 0". The face of this disk is numberedconsecutively the same as all counters of a similar character, so as to indicate ten complete rotations of the pointer c, at which moment a pin 8 of said disk turns a second disk S the distance of one tooth. This disk S has a tooth s, that operatesa third disk S", these three disks being sufficient to register 999 before requiring resetting. The combinations of numbers effected by these disks are exposed through suitable openings 0' in the dial.

T is a spring-pawl that prevents retrograde turning of the ratchet-wheel I.

Our register has been designed more especially for compelling drivers of oil-wagons to keep an accurate account of the quantity of oil delivered to grocers and other retail dealers. The oil is generally drawn from these tank-wagons in five-gallon buckets, which latter are emptied into barrels orother limited receptacles in groceries, &e.,and the driver is expected to charge each dealer with the exact quantity delivered to him; but disputes constantly occur between the retailer and the driver, and there is no means for determining which one of the two is right, because a record has not been preserved; but by adoptiug our register this difficulty is entirely obviated, as follows: The retailer secures the case A at a proper elevation and then notifies the driver that no oil will be paid for unless the bill tallies with the reading of the register, which is operated as follows: Every time a bucket is emptied into the retailers tank the driver is required to pull down the connection 7e as far as it will go and then release it suddenly, which simple act produces the following results: Assuming now that the pointer stands at 75, while the combination on the registeriugdisks indicates 962, as seen in Fig.1,a single pull of the lever J will advance said pointer to and so turn the first disk 8 as to expose the numeral 3. Consequently the reading on the dial will show that eighty gallons have been delivered since the register was last set, while the numbers exposed at the openings 0 will indicate that nine hundred and sixty-three buckets full of oil have been delivered since the machine was introdueed.

Every time the register is operated the groeers attention is called to the fact by a single blow being struck on the gong M, due to the descending tappet 76 coming in contact with the striking devices L, which audible notice is another check against any dispute in regard to the quantity of oil received.

The pointer travels around the dial until said device 0 reaches 100 and gradually winds the cord F upon the spool E,and as soon as said pointer has thus completed one entire rotation a pull of said cords turns the pointer backward to the starting-point. \Vhen this point is reached, the pin e of the spool strikes against the lug g of plate G and swings it as far as the slot g and stud b will permit, there by arresting the pointer at the proper place. The register has now been reset and ready to be again used, as above described, any possible travel of the pointer beyond the last nu1nber on the dial being prevented in the following manner: The instant the pointer reaches the number 100 the pin 6 strikes one edge of lug g and throws the plate G over in an opposite way as far as the slot g and stud b will allow, thus arresting said indicator 0; but if this position of the pointer should not be noticed, and repeated pulls be made on the lever J, the main shaft H will simply rotate within the sleeve D, while the latter remains immovable. Therefore there is no danger of injuring our register by pulling on the cord 70 after the pointer c has reached its limit; but, although no registry is now made on the dial, the registering-disks S S S perform their regular duties and will continue to do so until their combinations are exhausted, and then they will require resetting, which act is accomplished by temporarily disengaging the pawl R from the registering-disk S and then turning the three disks S S S backward until they all stand at 0, and then said pawl is re-engaged with said disk. Evidently a greater or less number of these disks may be employed; but three of them will indicate almost five thousand gallons delivered, and this is as much oil as most gro cers dispose of in a year, and on'this account a complete resetting of the entire register will be necessary only at long intervals of time. Finally, the object of the slot g is to allow the plate G to swing just so far as to arrest the pointer 0 when it is exactly at the limit of its forward and backward stroke.

We claim as our inventiou-- The combination, in a register, of a dial 0; a pointer 0, adapted to travel around said dial; a sleeve D that carries said pointer; a spool E, to which said sleeve is attached; a shaft H around which said sleeve turns; a ratchet-wheel I fastened to said shaft; a lever Jj, for operating said ratchetwheel; a stopplate G g g hung upon said sleeve; and a fixed stop I), that occupies the slot g, of said plate, for the purpose described.

In testimony whereof we aflix our signatures in presence of two witnesses.
